MACHINE :FOR SETTING HEEL AND SOLE rRo'rECToRS.

WIN TER, a

citizen of the United States, residing at' Lawrence, in the county ofEssex, State of Massachusetts, have in vented a certain new and usefulImprovement in Machines for Setting Heel and Sole Protectors, of whichthe following is a specification, reference being had therein to theaccompanying drawings. Y The invention relates to machines for drivingor setting metallic reinforces or protectors into the heels and soles ofboots andl shoes for the purpose of retarding and equalizing the Wearthereof.

More especially, the invention has relation to the devices which areemployed in such machines for presenting and positioning the protectorsor reinforces preliminary to the driving thereof, and assuring that theprotectors orreinforces shall be driven in the proper position into thestock which re-V ceives the same.

The invention consists in the features which I will now proceed todescribe with the aid of the accompanying drawings, in which latter Ihave illustrated the best forms in which the invention has thus far beenembodied.

The characteristic features of the invention will be particularlypointed out and distinctly defined in the claims at the close of thisspecification.

In the drawings, Figure 1 is a view in vertical section of portion of aprotectorsettingmachine having one embodiment of the invention appliedthereto, only so much of the machine being shown as is necessary inorder to properly disclose the nature and relations of the invention.Fig. 2 shows in plan the protector-transferring, holding and guidingdevices pertaining to the said embodiment, the slides being in theirretracted and open position represented in Fig. 1.

,are intended to be driven with the aid of the devices embodying theinvention.

Extensive use is made in practice of reinforces or protectors which areformed of bent strips of metal, these being applied by being drivenedgewise into the leather of the top-lift of a heel, or that of asole,.until the edges thereof remaining visible are flush with the outersurface of the top-lift or sole, or substantially so. 1, Fig. 15designates a forni of reinforce or protector of this general class, itbeing substantially of horseshoe shape, with one edge 2 thereof formedsufficiently thin to enable the Same to penetrate readily the leatherinto which the reinforce or protector is driven, while the other edge 3thereof is somewhat thicker. Edge 2 may be termed the entering edge ofthe device, while edge 3, which is exposed at the face of the Work intowhich the reinforce or protector is driven, and primarily receives thewear, may be vtermed the wear-receiving Hereafter the term protectorwill be It will be understood that while I have vshown only one wellknown form of protector, the invention is equally serviceable inconnection with other more or less varying forms of protectors. Theshowing in Fig. 15 therefore will be understood as being merelyillustrative of one variety of the device that is referred to herein asa protector.

Fig. 14 shows in plan the top-lift of a heel for a boot or shoe having aseries of protectors driven into the saine. In this case threeprotectors are shown, this being a number that frequently is employed inpractice, and they occupy positions in the toplift at one side of thelongitudinal axis of the lift and stand approximately radial withreference to the curved rear portion of the lift.

It will be obvious that in being driven the protectors have to be soheld and guided as to cause the entering edge of each to rest on orstrike the surface of the leather fairly, and also so as t-o cause theprotectors to take the proper position in the stock. If the protectorshould occupy an inclined position in being driven the work would bespoiled, while if the protector in being presented to the driver shouldbecome swung around transversely with respect to its intended posit-ionit would not be driven in the proper position into the leather, andthereby the appearance of the work would be injured. Protectors of theform illustrated in Fig. 15 are essentially U-shaped, and heretofore inmachines devised for the purpose of automatically driving or setting thesame, they have been guided and positioned by means of a rib or iinprovided in the machine adjacent the driving point in the latter, uponthe exterior of which rib or fin the protector has been caused to slide,the said rib or 1in passing into the opening of the protector andconstituting an internal guide for the latter while being driven. Theuse of this internal guide has been found disadvantagcous in practice,since it has necessitated the use of a driving pin or driver made U-shaped in cross-section at its driving end in order to clear thesaid ribor fin while forcing the protector into the stock. A U- shaped driver isfrail and subject to injury, and it has been necessary in machinesemploying the same to replace the drivers repeatedly. The breakages andother injuries to the drivers interfere with the use of the machines andlessen their capacity and productiveness, while considerable expense hasbeen entailed in replacing the drivers by new ones.

My present invent-ion simplifies the machines which are employed fordriving or set-ting protectors, dispensing entirely with the internalguides located at the driving points in the machines, and enabling theU-shaped drivers to be replaced by solid drivers. rIhese last arepractically free from liability to breakage or injury in the use of themachine, and hence rarely, if ever, require to be replaced.

In the drawings the drivers are shown at 5, in Fig. 1 and also in Fig.9. rIhe number of drivers employed in a machine may vary in practice,but inasmuch as usually inthe case of toplifts of heels, threeprotectors are driven in a group as indicated in Fig. 14, it may bestated that three drivers 5 ordinarily will be employed in a machineused in driving or setting protectors into toplifts.

The drivers 5, 5, are secured to a driverblock 6, Figs. 1 or 9. Theyextend downwardly from the latter. The driver-block 6 is applied to orformed on the plunger 8, the latter moving in suitable guideways 81,which are provided in the head 9 of the machine, the said plunger beingactuated in any suitable or approved manner, as for instance by means ofa crank-pin 10 carried by an operating shaft- 11, the said crankpinbeing represented as furnished with av roll 12 working in a transverseslot- 121 with which the plunger 8 is furnished. As indicated in Figs. 1and 9, the drivers 5, 5, are solid.

For the purpose of conveying the protectors to the place in the machineat which the drivers are arranged to act, suitable guides or racewaysare provided as at 13, 13. These correspond in number with the drivers,and in practice protectors are applied to the guideways by hand orotherwise as preferred so as to furnish the necessary supply. Herein theguideways are shown constituted by strips which are suitably supportedin proper position yin thc machine. A series of protectors is caused tostraddle one edge of each of the said guideways.

15 is a block which is mounted in the machine in position below thedrivers 5, 5, it being formed with a series of driver-passages 16, 1G,through which the protectors are driven into the stock which is toreceive the same. The said stock is held in contact with the lowersurface of the said block 15 at the time of driving. The block is showncarried by the head of the machine, and beneath the same is shown awork-supporting post 17, upon the up 3er end of which is mounted awork-rest 171 to receive the piece of stock which is to have protectorsdriven into the same. In practice, after the stock has been placed onthe work-rest 171 at the top of the work-supporting post 17, the latteris forced upwardly so as to compress the stock against the under surfaceof the block 15. I have not shown the means of forcing the post 17upwardly, inasmuch as the same forms no part of the invention and anyconvenient means of communicating vertical movement to the post 17 forthe purpose of thus compressing the stock and of afterward releasing thelatter may be employed in practice.

Above the block 15 formed with the driver-passages 1G, 16, I place apair of plates 20, 21. These are mounted to slide transversely withreference to the said block and its driver-passages. I have herein shownthe block 15 recessed in the top thereof to receive the plate 20, andthe plate 20 in like mann-er recessed to receive the plate 21. rIheblock and plates being thus nested together they are held in theirproper relationship by means of gibs 22, Q2, which are secured by screws23, 23, to the block 15 at opposite Sides of the recess therein andover- 2 and 4 applied to the block 15 acts on the L plate 20 with atendency to move the same to the rear in the machine. That is to say, tothe right in Fig. 1. Plate 2() is constructed to permit of the passageof protectors therethrough. To this' endi it is formed with one or moreopenings or passages extending vertically through the same f as at 25,Fig. 2. At one side of the said passage or passages 25 the plate 20 isprovided with a surface or surfaces 26 for engaging with the protectors.The plate 21v is likewiseformed with a surface or surfaces 27 forengagement with the protectors.` The normal position of the plates 20,21, relative to the block 15 is as represented in Figs. 1, 2 and 3, thepassage or passages through the plate 20 being located beneath the lowerends of the raceways 13, 13, and above a solid portion of the block 15to the rear of the driver-passages 16, and the plate 21 being moved tothe rear, also,- relatively to the plate 20 so as to separate theengaging surfaces 26, 27 to the maximum extent. As

the parts move rearwardly into this position, the bottom protectors onthe raceways,

the said protectors having previously been supported by the top of plate21, are capable of sliding or dropping from the said raceways into thepassageway or passageways of the plate 2O until the bottom protectorrests on the upper surface of the block 15. I provide means of causingrelative movement of the parts which will cause the protectors in thesaid passageway of plate 20 to be clamped between the opposing engagingsurfaces 26, 27, and then be carried forward in the machine so as toplace them above the driver-passages 16, 16, and in line with thelatter. Herein Ihaveshown a simple arrangement for the purposecomprising a lever 28, suitably hung to the head` of the machine, asupon a pin or pivot 29, and provided with a nose 30 arranged to be actedupon by a suitable moving part in the machine. In the present case thesaid nose is arranged to bear against the front of the plunger 8 underthe action of a spring 31. In the construction of machine which is shownin'Fig. 1, the prominent portion 32 on the plunger acts inthe rise ofthe latter as al cam to move lever 28 to retractthe plates 20, 21 andhold them in the positions relative to the block 15 and to each other inwhich they are represented in Fig. 1. The

depressed portion 33 of the plunger in the.

descent of the latter allows the spring 31 to act to move the lever toshift plates 21 and 2O relatively to the block 15 so as to cause f'theprotectors, first to be' clamped between fthe engaging surfaces 26` 27of the two plates, and then be carried along upon the 1 block 15 intoposition in linek with and above lthe driver-passages' 16, 16.

As the two plates move forwardly the solid part of plate 21 passes underthe next to the bottom protector on each raceway and supports the sameand the others above the same on 1 the respectiverac'eways until in theretrac- 'tion ofV the plates the' passageway or passageways in thelatter are presented again beneath the ends of the raceways. n

The engaging surfaces 26, 27 of the plates 20, 21, are so shaped withreference to the shape or Vform ofthe eXteriors o-f the protectors asthat when the said surfaces are caused to approach each other bymovement of the plates relatively to each other the contact of the saidsurfaces with the no-n-circular eXteriors of the protectors operatesautomatically to position the protectors prior to being driven. That isto say, the

said engaging surfaces 26, 27 are so shaped that whenthey are operatedto clamp upon the protectors theycause the latter to adjust themselves,in case they shouldvnot stand eX- actly as in Fig. 14 until they' standin precisely the positions which theprotectors are required to assume inthe stock. Some yconsiderable variation in the shapes of the engagingsurfaces 26, 27 vis possible. In Figs. 2 to 6, the engaging surfaces 26are constituted by the surfaces of recesses shaped to receive the openends of the protectors, the said open ends passing into the saidrecesses and the extreme ends of the sides of the protectors abuttingagainst the straight inner surfaces of the said recesses. The engagingsurface or surfaces 27 of the plate 21 are shown formed with concavitiesreceiving the convex back portions of the protectors. Protectors droppedfrom the ends of the raceways into the passageway or passageways of theplate 20 and restingv on the upper surface of the block 15, may, and inpractice frequently do, occupy positions varying considerably Afrom thatwhich they finally are required to assume in the stock, but when themovement of the plates relative to each other takes place, the clampingof the protectors between vthe engaging surfaces 26, 27, will cause theprotectors to so swing around transversely in a plane parallel with theentering edge ofa protector, and thereby re-adjust themselves inconsequence of the pressure of the said surfaces against the prominentportions of the protectors, more especially at the open end of theprotector, asv to give the protectors the same position which theyshould have in the stock. VHence, when the protectors subsequently aredriven into the stock they -conform to requirements and present therequired appearance.

lIt will be understood that the spring 31 acting on the lever 28 is morepowerful than the spring 24, Fig. 2, applied to the driverbloclr 15 andacting against the plate 20.

.In Figs. 1 to 6 when spring 31 is permitted to lact to move the lever,the action is first to move plate 21 upon plate 20 until the protectorshave become firmly clam ed between the engaging surfaces 26 and 2 afterwhich the spring 24 yields and the plates 20 21 move together untilprotectors held by said plates are brought over the driver passages 16.See Figs. 2 and 6. This occurs during the descent of the plunger anddrivers, and the plates 20, 21, remain in this position until theplunger and drivers complete their descent and begin to rise again. 'Bythe descent of the drivers 5, 5, the protectors are forced from theplates 20, 21 through the driver passages 16 and into the stock clampedbetween the work-rest 171 on the post 17 and the block 15. As theplunger rises and the prominent portion 32 of the plunger acts to movethe lever 28, the said lever moves the plate 21 toward the right inFig. 1. The plate 20 is moved in the same direction under the action ofthe spring 24, the extent of movement of the said plate 2O in suchdirection being limited, however, by means of a stop-pin 201, Figs. 2 to6, projecting from block 15 into a slot 202 in plate 20, the said pinand slot being represented in dotted lines in said figures.

In some cases I dispense with the use of the spring 24 carried by theblock 15 and acting against the plate 20, and instead thereof cause thesaid plate 2O to be held otherwise, as frictionally, so that it will notmove relatively to the block 15 until a sufficient amount of power isapplied thereto to overcome the resistance due to t-he friction. Thus,in Figs. 9 to 13, I provide'for producing a sufficient degree offriction against the plate 20 by means of a friction spring 41, seatedin a recess 42 in the edge of plate 20 and compressed between the saidedge and the adjacent side of the recess in the block 15 containing thesaid plate 20. In the case of the construction illustrated in thefigures just mentioned, the spring 31 acting on lever 28, when permittedby the depression 43 of the plunger 8 to move the said lever, acts inthe rise of the plunger first to move plate 21 relatively to plate 20until the protectors have become com ressed between the engagingsurfaces 26, 2 after which the frictional resistance to the movement ofplate 20 being overcome, the plates 2O and 21 move in unison into theirforemost position, thus placing the protectors above the driver passages16, 16. This takes place as the drivers approach their highest position.The prominence 44 of the plunger acts during the descent of the plungeragainst the lever 28 to turn the same in opposition to the spring 31.The first result of this is to move the plate 21 upon plate 20, thelatter remaining stationary. Thereby, the protectors are released andpermitted to drop into the driver-passages, 16, 16. In consequence ofthe engagement of lip 45 of the plate 21 with the plate 20, the furthermovement of the lever 28 acts to cause plate 20 also to be retracteduntil plates 2O and 21 have been given their former position to therear, with the passage 25 of the plate 2O in place below the lower endsof the raceways. This retraction of the plates 2O and 21 occurs in Fig.9 during the first portion of the descent of the plunger and drivers.

Figs. 7 and 8 show certain modifications which may be made in the formof engaging surfaces 26 of the plate 20. In Fig. 7 I have representedthe plate 2O as formed with a simple curved surface 261 in lieu of therecesses first described. The contact of the extreme ends of the sidesof the protector with this curved surface 261, as the said ends areforced against such surface by the relative movement of the plate 21 andits engaging surface 27, causes the protectors to right themselves bothvertically and horizontally in readiness for being driven. In Fig. 8 Ihave shown slight conveXities at 262, 262, against which the open endsof the protectors are caused to take bearing, a slight convexity at eachplace being all that is required in order to cause the protectors toright themselves These prominences or conveXities are intended simply toact against the eXtreme ends of the sides of the protector at theopening thereof, and it is not necessary that they should enter into theinterior of the protector.
